Description
Technical field
The present invention relates to data access method and Configuration Management Database (CMDB) system.
Background technology
As defined in the ITIL (IT Infrastructure Library, IT infrastructure storehouse), the configuration among the IT and management concentrate on the information of the configuration that administers and maintains relevant IT architecture.This information stores is in Configuration Management Database (CMDB) (CMDB, ConfigurationManagement Database).Described CMDB is the crucial integrated point around its integrated IT process.The target of CMDB is the single logic warehouse of all IT Asset Allocations that has in storage organization and the service, and provides accurate information about configuration and file to support other all Service Management processes.
Existing C MDB has two kinds of data access patterns: data integration (dataconsolidation) pattern and data aggregate (data federation) pattern, use different patterns at data of different types.
The data integration pattern was obtained data and is stored in the Configuration Management Database (CMDB) from data source according to the predetermined update cycle, when the data access request received from client computer, the data of storage are offered client computer and non-access data sources to obtain data in real time.Therefore, the data integration pattern is primarily aimed at those data that not too change, for example: machine sequencing number, configuration information.Yet the major defect of data integration pattern is that data lag behind.Between the update cycle of integration process, in the data source change of data frequent more, it is outmoded more that the data among the CMDB will become.Therefore, lack the currency or the consistance of data instance, the data that the user obtains from CMDB may be inconsistent with the current data in the data source.
On the other hand, the data aggregate pattern provides a kind of middleware, makes application can visit the data from the different pieces of information source, just looks like from the individual data source, and no matter position, form and the access language of data.Different with the data integration pattern, the data aggregate pattern data that physically storage is not obtained from data source in CMDB, but visit different data sources in real time according to data access request, then the data of obtaining are offered client computer.Therefore, the data aggregate pattern is used for real time data mostly, and speed is fast, and cost is little.Yet the major defect of data aggregate pattern is the availability of data.That is, if data source is unavailable, such as data source fault or shutdown or the CMDB interruption that is connected with data source, the user can not obtain data so.
Fig. 1 shows the system block diagram of Configuration Management Database (CMDB) in the prior art.As shown in Figure 1, CMDB links to each other with data source A-Z and client computer A-C by network or other connected mode.For example, CMDB receives data access request from client computer A, and the type of the data of asking according to data access request determines to use the data integration pattern.Then CMDB will be stored among the CMDB before the data obtained by data integration mode access data source A and C offer client computer A.Yet according to the update cycle of data integration pattern, the data that offer client computer A may be several days or a few week or even some months data before, and also inconsistent with the current data among data source A and the C.But whether the user is can not judgment data credible, thereby may make unsuitable decision-making according to the data of obtaining.
Again for example, CMDB receives data access request from client computer C, and the type of the data of asking according to data access request determines to use the data aggregate pattern, CMDB access data sources B and Z in real time then, and the data of obtaining are offered client computer.Yet, may can not obtain data from data source B or Z owing to connect interruption.Fig. 2 A and Fig. 2 B show the example of presenting to the user's data integrated view in this case.Wherein, Fig. 2 A is the form of tabulation, and Fig. 2 B is histogrammic form.This example is the assets report about the current assets value of obtaining from 5 different computing machines.Fig. 2 A shows fully qualified name, IP address, Machine Type and the current assets value of each computing machine.Horizontal ordinate among Fig. 2 B is represented current assets value, and ordinate is represented the fully qualified name of each computing machine.From Fig. 2 A and Fig. 2 B, as can be seen, have the currency of 3 computing machines to be " N/A or 0 ", this be since computer failure or computer shutdown or with CMDB be connected interruption etc. former thereby can't from these computer real-time get data.Therefore, the user can not obtain the data of wanting.
